Since the screw thread is formed so that the anchor angle adjustment unit 230 and the anchor extension unit 210 are helically coupled, the anchor angle adjustment unit 230 can be moved while spirally rotating along the longitudinal direction of the anchor extension unit 210 .

And the lower surface of the anchor angle adjusting unit 230 is configured in a concave hemispherical shape to match the convex hemispherical shape of the upper end of the anchor rotating unit 221, so that the lower surface of the anchor angle adjusting unit 230 is spherically coupled with the upper end of the anchor rotating unit 221 can be adhered to.

In this state, when the anchor pillar part 200 is inclined at a predetermined angle, the anchor extension part 210 is also inclined in the same way. As the spherical rotation of the part 230 is made along the upper surface of the anchor rotating part 221 , the anchor extension part 210 is smoothly angularly adjusted in a state coupled to the anchor support plate 220 . adjustment can be made.

Now, when the angle adjustment is finished, the anchor angle adjustment unit 230 is rotated in one direction so that the anchor angle adjustment unit 230 is in close contact with the upper surface of the anchor support plate 220 and is tightened. And the anchor extension 210 is fixed in shape as it is coupled to the anchor support plate 220 .

At this time, the anchor extension part 210 is in a state of being elongated as it extends downward from the anchor pillar part 200, and the lower end of the anchor extension part 210 is connected to the anchor support plate 220 by the anchor support plate 220, although the anchor extension It is necessary to reinforce the force capable of maintaining and supporting the gap between the parts 210 .

It is rotated to be inclined downward to match, and a fastening member is mounted on the hinge hole 301 of the hinge coupling part 330 to fix the bent coupling state of the underground upper frame 300 and the upper extension frame 320 .

At this time, the both ends of the subterranean upper frame 300 and the joint end portion of the upper extension frame 320 corresponding to the front end of the hinge coupling part 330 to be able to rotate smoothly with the hinge coupling part 330 as the center. Each tip is configured in a round type or V-shaped, and the hinge coupling part 330 and the hinge hole 301 may be formed on the other closed side without an open part, and the other side surface on which the hinge coupling part 330 is formed. Around one side, the upper surface, and the lower surface are cut, and only the other side on which the hinge coupling part 330 is formed is provided. A smooth hinge rotation can be achieved in a state in which the is coupled.

As a result, the anchor extension 210 extends to the lower portion of the underground upper frame 300 and the lower underground frame 400 on the lower extension line of the base 100, and when installed, the upper extension frame at both ends of the underground upper frame 300 (320) is extended and installed by being bent downward, it is possible to balance the overall balance in an additional embodiment according to the extension of the anchor pillar (200).
